Abstract

The invention relates to a mechanism for an earth fault current circuit breaker combined with a line circuit breaker. In this case, the intention is to design an earth fault current circuit breaker which can be combined with one or more already known line circuit breakers. In contrast to the known earth fault current circuit breakers, it is intended to use only a small number of structurally uncomplicated components. The solution consists of a rotationally moving trip plate 6 which is effectively connected to an operating member 5 of the trip device 4, a return plate 15, which is subject to the pressure of a spring 20, and a trip lever 13 for the earth fault current circuit breaker, the return plate being connected in a hinged manner via a return clip 21 to a transmission member which is constructed as a switch-off clip 25 for the line circuit breaker. The single latching point in the earth fault current circuit breaker consists of the trip lever 13 which operates in conjunction with a latching lever 27. During tripping, the spring 20 fulfils a double function, namely returning the trip device 4 and switching off the line circuit breaker. <IMAGE>

Description

Die Erfindung betrifft einen Mechanismus für einen mit einem Leitungsschutzschalter kombinierten Fehlerstromschutzschalter gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a mechanism for a residual current circuit breaker combined with a line circuit breaker according to the preamble of claim 1.

Ein derartiger Mechanismus ist bereits bekannt (DE-PS 29 04 211). Bei diesem Mechanismus sind konstruktive Maßnahmen vorgesehen, die die Wiedereinschaltung des auf einen Fehlerstrom ansprechen­den Auslöserelais mit großer, jedoch sehr weich einzuleitender Kraft bewirken, so daß ein Zerschlagen der empfindlichen Polflä­chen des meist nach dem Kraftprinzip arbeitenden Auslöserelais vermieden wird. Hierzu wirken zunächst zwei Federn nach dem Ent­klinken des Auslösemechanismus auf den Verschwenkvorgang des Schalthebels, der dadurch mit großer Kraft das Übertragungsglied, das die Mechanismen der Leitungsschutzschalter betätigt, ansteu­ern kann. Erst nach anfänglichem Verschwenken des Schalthebels erfolgt die Mitnahme des Klinkenhebels und damit das selbsttätige Wiedereinschalten des Auslöserelais. Zum Erreichen des gesteck­ten Ziels sind allerdings zahlreiche Bauteile und drei Verklin­kungsstellen erforderlich.Such a mechanism is already known (DE-PS 29 04 211). In this mechanism, constructive measures are provided which cause the triggering relay, which responds to a fault current, to be switched on again with a large but very soft force, so that the sensitive pole faces of the triggering relay, which usually works on the force principle, are avoided. For this purpose, two springs initially act on the pivoting process of the switching lever after the release mechanism has been released, which can thereby actuate the transmission element which actuates the mechanisms of the circuit breaker with great force. Only after the switching lever has been pivoted initially, the ratchet lever is carried along and thus the trigger relay is automatically switched on again. However, numerous components and three latching points are required to achieve the set goal.

Es ist auch ein Mechanismus für einen mit einem Leitungsschutz­schalter kombinierten Fehlerstromauslöser bekannt, der einen vom Leitungsschutzschalter getrennten Handbedienungsknebel, ein von einem Mechanismusteil rückstellbares Auslöserelais und ein auf die Verklinkung des Leitungsschutzschalters einwirkendes Über­tragungsglied aufweist (DE-OS 31 07 687). Die Verringerung der Einzelteile führt allerdings zu recht komplizierten und auf­wendigen Bauelementen, wozu besonders der Klinkenhebel zählt, da dieser mit wenigstens 3 anderen Bauelementen korrespondiert und eine mit einer Stahlkugel bestückte Klinkennase besitzt. Auch müssen die Aufnahmen des zweifach gebogenen Kupplungsbügels, der als Verbindungsglied zwischen dem Fehlerstromauslöser und dem benachbarten Leitungsschutzschalter dient, sehr sorgfältig ausgeführt werden, da sonst die Gefahr des Verkantens besteht.A mechanism for a residual current release combined with a miniature circuit breaker is also known, which has a manual control toggle separate from the miniature circuit breaker, a trigger relay that can be reset by a mechanism part, and an on the latching of the circuit breaker acting transmission member (DE-OS 31 07 687). However, the reduction in the number of individual parts leads to quite complicated and complex components, which particularly includes the ratchet lever, since this corresponds to at least 3 other components and has a ratchet nose equipped with a steel ball. The recordings of the double-curved coupling bracket, which serves as a connecting link between the residual current release and the adjacent circuit breaker, must also be carried out very carefully, otherwise there is a risk of jamming.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Fehler­stromschutzschalter der zuvor geschilderten Art mit dem Ziel zu schaffen, mit möglichst wenigen und unkomplizierten Bautei­len und mit einem Minimum an Verklinkungsstellen auszukommen.The object of the invention is therefore to create a residual current circuit breaker of the type described above with the aim of using as few and uncomplicated components as possible and with a minimum of latching points.

Diese Aufgabe wird erfindungsgemäß durch die im Kennzeichen des Anspruchs 1 angegebenen konstruktiven Maßnahmen gelöst.This object is achieved by the design measures specified in the characterizing part of claim 1.

Die mit der Erfindung erzielten Vorteile bestehen unter Aufrecht­erhaltung der Sicherheit und der Zuverlässigkeit in einem wesent­lich vereinfachten Herstellungsverfahren.The advantages achieved with the invention consist in maintaining the safety and reliability in a substantially simplified manufacturing process.

Eine besonders vorteilhafte Ausgestaltung des Gegenstandes nach Anspruch 1 ist im Rückführungsblech zu sehen, das nicht nur für die Rückstellung der Auslöseeinrichtung verantwortlich ist, sondern auch einen Rückstellbügel trägt, der indirekt für die Auslösung des Leitungsschutzschalters zuständig ist. Hierbei spielt eine Feder, gegen deren Druck das Rückführungsblech be­wegbar ist, eine entscheidende Rolle.A particularly advantageous embodiment of the object according to claim 1 can be seen in the return plate, which is not only responsible for the resetting of the triggering device, but also carries a reset bracket, which is indirectly responsible for triggering the circuit breaker. Here a spring, against the pressure of which the return plate can be moved, plays a decisive role.

Ein Ausführungsbeispiel der Erfindung ist in einer Zeichnung dargestellt und wird im folgenden näher erläutert. Es zeigt die Figur einen Fehlerstromschutzschalter in Seitenansicht, bei ab­genommener Seitenwand.An embodiment of the invention is shown in a drawing and is explained in more detail below. The figure shows a residual current circuit breaker in side view, with the side wall removed.

Nach der Figur ist der Mechanismus des Fehlerstromschutzschal­ters in einem Gehäuse 1 untergebracht, dessen sichtbare Seiten­wand 2 an einen benachbarten Leitungsschutzschalter (nicht dar­gestellt) grenzt. In dieser Seitenwand befindet sich ein Schlitz 3, der für ein Übertragungsglied vom Fehlerstromschutzschalter zum benachbarten Leitungsschutzschalter vorgesehen ist. Für die Auslösung des Fehlerstromschutzschalters ist eine Auslöseein­richtung 4 vorgesehen, welche die elektrische Energie in eine mechanische Energie umsetzt. Hierzu besitzt die Auslöseeinrich­tung ein Betätigungsglied 5, das im Auslösefall auf ein Auslöse­blech 6 einwirkt. Dieses Auslöseblech ist im Querschnitt etwa L-förmig ausgebildet, wobei sein längerer Schenkel 7 mit einem Auslösehebel 13 korrespondiert und der kürzere Schenkel 8 end­seitig derart umgebogen ist, daß ein kleines Stück dieses Schen­kels parallel zum längeren Schenkel verläuft und damit einen An­schlag 9 für das Betätigungsglied 5 bildet. In der Mitte des längeren Schenkels weist das Auslöseblech eine abgewinkelte Lasche 10 mit einer Bohrung auf, die ein Aufstecken des Auslöse­blechs auf eine gehäusefeste Achse 11 gestattet. Das Auslöseblech steht unter der Wirkung einer Drehfeder 14.According to the figure, the mechanism of the residual current circuit breaker is housed in a housing 1, the visible side wall 2 of which borders on an adjacent circuit breaker (not shown). In this side wall there is a slot 3, which is provided for a transmission element from the residual current circuit breaker to the adjacent circuit breaker. A triggering device 4 is provided for triggering the residual current circuit breaker, which converts the electrical energy into mechanical energy. For this purpose, the trigger device has an actuating element 5, which acts on a trigger plate 6 in the event of a trigger. This release plate is approximately L-shaped in cross section, its longer leg 7 corresponds to a release lever 13 and the shorter leg 8 is bent at the end such that a small piece of this leg runs parallel to the longer leg and thus a stop 9 for the actuator 5 forms. In the middle of the longer leg, the release plate has an angled tab 10 with a bore, which allows the release plate to be plugged onto a shaft 11 fixed to the housing. The trigger plate is under the action of a torsion spring 14.

Ein Rückführungsblech 15 besitzt endseitig ein rohrförmiges Teil 16, welches eine gehäusefeste Achse 17 umschließt. Im mittleren Bereich weist das Rückführungsblech eine abgewinkelte Lasche 18 mit einer Bohrung auf, die zur Aufnahme eines Rückstellbügels 21 dient. Am freien Ende ist das Rückführungsblech derart abgewin­kelt, daß es im eingeschalteten Zustand des Fehlerstromschutz­schalters etwa senkrecht auf dem Auslöseblech 6 unterhalb des Drehpunktes steht. Die Bewegung des Rückführungsblechs erfolgt gegen die Wirkung einer Konusfeder 20.A return plate 15 has a tubular part 16 at the end, which encloses an axis 17 fixed to the housing. In the middle area, the return plate has an angled tab 18 with a bore, which serves to receive a reset bracket 21. At the free end, the return plate is angled in such a way that when the residual current circuit breaker is switched on, it is approximately perpendicular to the trip plate 6 below the pivot point. The movement of the return plate takes place against the action of a conical spring 20.

Der Rückstellbügel 21 ist an seinem freien Ende kreisförmig ab­gebogen und umschließt einen zylindrischen Stift 22. Gleichfalls sind mit diesem zylindrischen Stift ein Ausschaltbügel 25 für den benachbarten Leitungsschutzschalter und ein Zwischenglied 26 verbunden. Der zylindrische Stift gleitet in einer beidseitigen Schaltkulisse 24, die einmal von der Rückwand 2 und zum anderen von einer Zwischenplatte 30 (nicht dargestellt) gebildet wird. Die Bewegung des zylindrischen Stifts erfolgt bei der Einschal­tung gegen die Wirkung einer Drehfeder 23, die gleichzeitig den Auslösestrom bei Betätigung der Prüftaste führt. Das Zwischen­glied steht über einem Bügel 28 mit dem Einschalthebel 29 des Fehlerstromschutzschalters in Verbindung. Mit dem Zwischen­glied ist ferner ein Verklinkungshebel 27 verbunden, der die Verklinkungsstelle mit dem Auslösehebel 13 bildet, der unter der Wirkung einer Drehfeder 14 steht.The reset bracket 21 is bent at its free end in a circle and encloses a cylindrical pin 22. Likewise, a switch-off bracket 25 for the adjacent circuit breaker and an intermediate member 26 are connected to this cylindrical pin. The cylindrical pin slides in one on both sides Switching gate 24, which is formed on the one hand by the rear wall 2 and on the other hand by an intermediate plate 30 (not shown). The movement of the cylindrical pin takes place when it is switched on against the action of a torsion spring 23 which at the same time carries the trigger current when the test button is pressed. The intermediate link is connected via a bracket 28 to the switch lever 29 of the residual current circuit breaker. A latching lever 27 is also connected to the intermediate member, which forms the latching point with the release lever 13, which is under the action of a torsion spring 14.

Da der Fehlerstromschutzschalter über keinerlei Schaltkontakte verfügt, muß der benachbarte Leitungsschutzschalter das Schal­ten der Kontakte übernehmen, d.h. beide Schalter müssen einge­schaltet werden. Der Leitungsschutzschalter kann auch bis zu einer vierpoligen Ausführung eingesetzt sein. Das gleichzeitige Ein- und Ausschalten einer mehrfachen Kombination von Hand er­folgt durch untereinander gekoppelte Einschalthebel. Beim Aus­schalten im Fehlerfall lösen alle Leitungsschutzschalter gleich­zeitig aus, da die Auslösehebel aller Leitungsschutzschalter miteinander in Wirkverbindung stehen.Since the residual current circuit breaker has no switch contacts, the adjacent circuit breaker must take over the switching of the contacts, i.e. both switches must be turned on. The circuit breaker can also be used up to a four-pole version. The simultaneous switching on and off of a multiple combination by hand takes place by means of mutually coupled switch levers. When switching off in the event of a fault, all miniature circuit breakers trip at the same time, since the release levers of all miniature circuit breakers are operatively connected to one another.

In einem Fehlerstromfall wird die Auslöseeinrichtung 4 derart beaufschlagt, daß das Betätigungsglied 5 nach außen tritt und das Auslöseblech 6 im Uhrzeigersinn bewegt. Damit wirkt das Ende des längeren Schenkels 7 auf den Auslösehebel 13 des Feh­lerstromschutzschalters ein, womit die Verklinkungsstelle zwi­schen dem Verklinkungshebel 27 und dem Auslösehebel 13 auf­gehoben wird. Damit kann der zylindrische Stift 22 in der Schalt­kulisse 24 in Richtung zum Auslösehebel 13 gleiten, womit gleich­zeitig der Ausschaltbügel für den Leitungsschutzschalter die Verklinkungsstelle im benachbarten Leitungsschutzschalter auf­hebt und die Schaltkontakte öffnet. Ferner wird mit diesem Vor­gang der Rückstellbügel 21 betätigt, so daß das Rückführungs­blech 15 das Auslöseblech 6 entgegen dem Uhrzeigersinn dreht und damit über das Betätigungsglied 5 die Auslöseeinrichtung 4 zu­rückstellt.In the event of a fault current, the triggering device 4 is acted on in such a way that the actuating member 5 moves outward and the triggering plate 6 moves clockwise. The end of the longer leg 7 thus acts on the release lever 13 of the residual current circuit breaker, with the result that the latching point between the latching lever 27 and the release lever 13 is removed. The cylindrical pin 22 can thus slide in the switching link 24 in the direction of the release lever 13, whereby the switch-off bracket for the circuit breaker simultaneously removes the latching point in the adjacent circuit breaker and opens the switching contacts. Furthermore, the reset bracket 21 is actuated with this process, so that the return plate 15 rotates the release plate 6 counterclockwise and thus resets the release device 4 via the actuator 5.

Im Überstrom- oder Kurzschlußfall wird nur der Leitungsschutz­schalter betätigt, während der Fehlerstromschutzschalter wegen seiner empfindlichen Auslöseeinrichtung im eingeschalteten Zu­stand verbleibt.In the event of an overcurrent or short circuit, only the circuit breaker is actuated, while the residual current circuit breaker remains in the switched-on state due to its sensitive tripping device.
